SPECIFICATION forming part of Letters `Patent No. 604,457, dated May 24, 1898.

Application led Tune 4, 1897.

To a/ZZ whom, t may concern:

Be it known that I, THOMAS CREBBIN, a citizen of the United States, residing at Bridgeport, in the county. of Jackson and State of Alabama,- have inventedaj new and useful Basket-Making Machine, of which the following is a specification.

My invention relates toV receptacle-making machines, and particularly to those adapted' for use in the manufacture of basketsof various kinds-.such as handleless vegetable and fruit baskets, covered and uncovered throughout the operation to provide for the detection of flaws either in the material or the workmanship, and thus avoid the inconven-A ience and loss of time incident to proceeding with the operation of completing an imperfect article, as when the same is concealed during the process of construction.

Further objects and advantages of this in-V vention will appear in the following descrip` tion, and the novel features thereof will be particularly pointed out in the appended claims.

Fig. 16 is a side view of a slightly-modified construction of machine wherein two devices are usedcoperatively. Fig. 17 is a detail plan view of the cam for operating the slide-actuating arm.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

Rising from a suitable base 1 are standards 2 and 3, provided with alined slots 4, in which are fitted for vertical adjustment the registering bearings 5 and 6, provided at one end with a fixed collar 51L 6a and at the other end with an adjustable collar 5b 6l. Mounted for rotary and sliding movement in said bearings is a folder-shaft 7, upon which is swiveled a loose collar 8, between suitable limitingpins 9. 4

Fixed to theshaft 7 is aspider 10, having arplurality of arms radiating from a hub 11, these arms being provided at their outer extremities with seats l2, in which are secured folder-arms 13, having beveled extremities, as shown at 14, connected by a band 13B and contiguous shoulders 15, formed by reducing the outer portions of the arms. The spider and folder-arms constitute one member of the folder for coperation with a second member, consisting of a form 16, this form having a hub extended to form a sleeve 17, which is fitted upon a spindle 18, extending horizontally from an upright 19, in alinement with the folder-shaft 7. The form also embodies a cylindrical open-ended shell 20, equal in diameter with the receptacle to be formed thereon and extended beyond the web 21, whereby it is connected with the hub to form the hollow semispherical iiange 22, through a central opening 23 in which projects the ex- IOO tremity of the spindle 18, said spindle being reduced beyond the plane of the opening 23 to form an engaging pin 24, which fits in a socket 25 in the hub of the spider.

The shell of the form is provided contiguous to its open end with a plurality of spaced openings 26, and said flange terminates in a circumferential enlargement or collar 27, having interior ratchet-teeth 28.

29 represents a feed-shaft mounted in suitable bearings in the uprights 19 and a similar adjacent upright 19a and carrying a feedarm 30, to which is pivoted a feed-pawl 31 to engage the ratchet-teeth on the form and thereby impart a step-by-step rotary movement to said form during the oscillation of the feed-arm. The feed-arm is preferably slotted, as shown at 32, to provide for adjustment of the pawl with relation thereto to suit forms of different diameters.

Oscillatory movement is imparted to the .feed-shaft by means of a reciprocatory plunger-stem 33, mounted in suitable bearings in the upright 19L and carrying a pin 34, which engages a slot 35 in a lateral arm 36 on said feed-shaft, and vreciprocatory movement is imparted to said plunger-stem by means of a continuously-operating driving-shaft 37, having a crank-disk 38, and a link or pitman 39 connecting said plunger-stem with the crank-disk.

The plunger or stapling-hammer 40, which is fixed to the upper end of the stem 33, is provided with a hammer-post 41, operating in a staple-guide 42 at the front end of a presserarm 43, a presser-roll 44 being mounted upon a horizontal axis in a bifurcation 45 in the presser-arm and being adapted to hold an exterior band of a basket or receptacle in contact with the outer surface of the mat contiguous to the plane of the enlargement or collar 27 of the form d urin g the rotation of the form, and said staple-guide being adapted to receive staples to be driven by the hammer through said band and mat in the operation of secu ring the former to the latter.

From the foregoing description it will be understood that the folder receives an intermittent or step-by-step rotary movement in a uniform direction during the operation of the machine, the movement thereof occurring during the upward reciprocation of the plunger-stem 33, and hence during the elevation of the hammer, whereas during the downward or operative movement of the hammer the folder and form remain stationary, the feed-pawl 31 slipping idly in a rearward direction over the succeeding ratchet-teeth of the form.

In connection with the fastening or stapling mechanism I employ an anvil to accomplish the clenchin g of the inner end of the staple-clip, nail, or other fastening device which may-be used to secure the parts of the receptacle together. In the construction illustrated the anvil 46 is bifurcated to form parallel depending legs 47, which operate in suitable vertical guides 48 in a horizontal anvilsupport 49, the upper end of said anvil being adapted to pass through the openings 26, hereinbefore described, which are provided in the shell of the form for this purpose, and the elevation of the anvil at the proper intervals-namely, during the descent of the hammer-is accomplished by means of an actuating-slide 50, mounted horizontally in said anvil-support 49 and provided with a beveled or cam face 51, formed on a reduced tongue 52 at the front end of the slide. This tongue operates in the interval between the depending legs'47 and the anvil, and the beveled or cam face 5l thereof engages the shoulder 53, which is formed between said legs at the lower end of the body portion of the anvil. The upper side of the tongue 52 forms a horizontal rest by which the anvil is supported during the driving of the staple or nail.

The anvil is preferably provided with a vertical seat 54, in which vis removably fitted a hollow die 55, said die `being provided with a downwardly reduced or tapered bendingseat 56 to receive the lower extremities of the staples when they have been driven through the wall of the basket or receptacle, the downward convergence Aof the walls of the seat serving to bend the points of the staple inwardlyor toward the center of the seat. The end walls of the seat are also preferably inclined or beveled transversely in opposite directions to throw the points of the staple out of alinement with each other as the staple is forced downward, and the seat 56 is extended to form a plunger-guide 57, in which operates the upper end of the clenching-plnnger 58. This clenchlng-plunger is provided with an enlargement or collar 59, arranged to operate in a cavity 60 in the die in communication with the guide 57.y The tongue 52 of the actuating-slide 50 is also longitudinally slotted, as shown at 6l, for the reception of a trip 62, which is pivoted at its rear end, and is adapted at its free end to ride upon a wedge block or cam 63, fixed to the floor-of the guide in which the slide 50 is fitted. As the slide 50 is advanced during the downward movement of the stapling-hammer the anvil is first elevated to enter the alined opening 26 in the shell of the form to bring the upper surface of the guide in contact with the inner surface of the wall of the receptacle opposite to the point at which the staple is to be driven. As the motion of the slide 50 continues it brings the plain or horizontal upper surface of the tongue 52 in contact with the shoulder 53 of the anvil,and thus forms a substantial support for the anvil, whereby the downward impact of the stapling-hammer is effectually resisted. As the motion of the actuating-slide 50 still continues, the stapling-hammer has reached its operative position and has forced the staple through the band and wall of the receptacle and has introduced the extremities of the staple into the bending-seat 56, the downward movement of said extremities, after entering IOO IIO

the seat, causing them to be bent to lie in different but contiguous planes and over the guide 57, and when the extremity of the trip 62 reaches the Wedge block or cam 63 the former is elevated sharply and brought into contact with the lower end of the clenching-plunger 58,which, rising into the bending-seat 56, turns the points of the staple and forces them into the material forming the wall of the receptacle.

The means illustrated in the drawings for operating the slide 50 consists of an oscillatory arm 64, fulcrumed, as at 65, in a suitable bracket supported bythe upright 19, the connection between the upper end of said arm and the slide being formed by a slotted fork 66 of the arm engaging a pin 67, carried bya depending ear G8 on the slide, and a pusharm 69, pivotally connected to the arm 64 at an intermediate point and having its beveled extrelnity arranged inthe path of a cam 70 on the reciprocatory stem 33. Said cam is of downwardly tapered or beveled construction and is elliptical or otherwiseirregularin plan, Fig. 17, whereby by rotary adjustment of the cam upon the stem greater or less throw may be imparted to the slide 50. Said cam is secured at the desired adjustment by means of a set-screw 7l. I

In Fig. 2 I have shown the reciprocatory member of the folder, comprising the spider and folder-arms, retracted to provide for the application to the center pin 24 of a plaited mat 72, which is designed to form the bodyportion of the basket or receptacle, said pin being inserted through a central perforation adapted to be formed in any convenient manner in the center of said mat. Before advancing said .reciprocatory member of the folder a middle hoop or band 73 is inserted between the reduced extremities of the folderarms and is arranged in contact with the shoulders l5 thereof. The shaft 7 is then advanced to fold the mat upon the form and bring the upper edge of the mat under the presser-roll 4:4 and contiguous to the shoulder formed by the enlargement or collar 27. The exterior top band 74 is then applied beneath the presser-roll and the operation of the mechanism proceeds, as hereinbefore explained.l

When the basket has been completed, it is necessary to remove it from the form in order to give place for a second mat, and in order to accomplish this I employ detaching or displacing arms 75, fulcrumed, as at 76, upon the spider, or preferably upon the rear extremities of the folder-arms 13, and provided with tapered outer extremities having shoulders 77 to engage the outer edge of the basket, as illustrated in Fig. 3, preparatory to retracting the reciprocatory folder member. The displacing-arms are provided with inturned trip extensions or fingers 7 S, disposed radially with relation to the shaft 7 and terminating at their inner ends contiguous thereto, whereby when the movable member of the folder is retracted,l as shown in Fig.\2, the

free extremities of the trip extensions encounter a stop formed by the collar 6b and are moved to the position indicated insaid Fig. 2, thereby spreading the displacing-arms and releasing the receptacle.

Owing to the fact that the exterior reciprocatory folder member is supported by an axial shaft attached to said folder member at its outer end and thereby preventing the removal of a completed receptacle at said outer end of the member, it is necessary to remove the receptacle at the opposite or inner end after the reciprocatory member has been withdrawn from operative relation with the fixed or interior folder member, and in order to accomplish the release of the receptacle after the retract-ion of the exterior folder member the displacing or stripping arms must be spread or moved outwardly from the folder member upon which they are mounted, the spreading movement being communicated to said arms by means located at the outer end of the exterior folder member and contiguous to the said axial shaft by which said folder member is carried. Owing to the arrangement of the displacing-arms and the arrangement of the means for operating the same, said means being located contiguous to the shaft by which the exterior folder member is supported, they cannot be substituted by the ordinary forms of stripper-arms known in the art and usually located within the exterior folder member to displace the receptacle from the inner folder member and then drop the receptacle for the reason, as above indicated, that in the construction disclosed herein the exterior member of the folder is mounted for reciprocation andis so constructedat its outer end, or that end which is remote from the interior folder member when the folder members are separated, as to prevent the axial removal of the receptacle in the same direction as it is forced into the exterior member. In displacing the receptacle it must be moved in the opposite direction, or toward the inner end of the exterior folder member.

As it is desirable to maintain the displacing-arms in their spread position during the folding and construction of the basket, I preferably employ a securing device, consisting of a disk 7 9, mounted for partial rotation upon the shaft 7, contiguous to the -hub of the spider, and provided with a plurality of radial slots or notches 80, through which the inner extremities of the trip extensions may pass. This disk is also provided with ahandie or operating-arm Si, and hence after the movable member of the folder has been retracted to the position shown in Fig. 2 a slight movement of the handle or operating-arm Sl will secure the displacing-arms in their spread position. Said arms remain in their spread position until after the folding of the blank from which the receptacle is to be formed, as shown in'Fig. l, and are released byasecond adjustment of the disk 79 only after the completion of the receptacle and when it is time IOO IIO

for the retraction of the movable member of the folder to remove said receptacle. The displacing-arms are yieldingly held in their operative positions and are returned to said positions when released by the retaining device 79 by means of actuating-springs 82.

The means illustrated in the drawings for actuating the reciprocatory member of the folder include a friction-wheel 88, having its shaft 84 mounted in sliding journal-boxes 85 on the base 1 or other suitable support, whereby said friction-wheel may be arranged in peripheral contact with a friction-wheel 86, which is fixed to the driving-shaft 37, an oscillatory lever 87, having its slotted extremity engaged with a lateral pin SS on the collar 8, and a pitman 89, connecting said arm S7 with a crank-disk 90 on the spindle 84 of the friction-wheel. A slotted connection is employed, as above indicated, between the oscillatory lever 87 and the collar 8, and an adjustable connection consisting of a slot 91 and a pivot-bolt 92 is employed between the pit-man and said oscillatory lever. Furthermore, inasmuch as the reciprocation of the movable member of the folder occurs only at such intervals as to provide for the removal of a completed receptacle and the application of ablank for a succeeding receptacle, it is desirable to employ shifting mechanism whereby the friction-wheel 83 may be arranged either in or out of contact with the friction-wheel 86, as required. An efficient means for accomplishing this operation is shown in the drawings and embodies a footlever 93, upon which is mounted a movable stop 94, actuated by a bell-crank lever 95, the extremity of the stop being arranged normally in the path ot' projections or ears 96, arranged on the friction-wheel 83 at diametrically opposite points, and the stops being yieldingly held in operative position with relation to said projections or ears by means of an actuating-spring 97. Mounted upon the foot-lever contiguous to its free end is a tilting foot rest or treadle 98, of which the toe portion is arranged in operative relation with the approximately horizontal arm of the bellcrank lever 95, whereby when the toe portion of said rest or treadle is depressed it actuates the bell-crank lever and withdraws the stop from the path of the projection or ear with which it is engaged. Also connected with the foot-lever is a toggle-lever consisting of arms 99 and 100, pivotally connected at their remote extremities, respectively, to a 'fixed object, as a bracket 101 on the base 1, and to the sliding journal-box 85, and pivot-ally connected at their inner extremities to a depending bracket 102 on the foot-lever. Hence when a receptacle has been completed the operator moves the handle or arm S1 of the retaining device to release the trip extensions 7S and bring the displacing-arms 75 into operative relation with said receptacle and at the same time the toe portion of the tilting foot-rest is depressed to disengage the stop 94 from the projection or ear 96 of the friction-wheel 83, and at the same time downward pressure is imparted to the lever 93 to raise the in ner extremities of the toggle-arms and force the bearing 85 toward the drivingshaft sufficiently to bring the friction-wheel 88 into peripheral contact with the disk 86. Said disk immediately imparts rotary motion to the wheel 83 and moves the lever 87 to retract the reciprocatory member of the folder, and thus displace the receptacle. As soon as the rotation of the friction-wheel has commenced the tilting foot-rest is allowed to resume its normal position, thus releasing the bell-crank lever 95 and allowing the stop 94 to extend into the path of the succeeding projection or ear 96 of thefriction-wheel, and therefore when said friction-wheel has made a complete half-revolution, thus bringing the reciprocatory member of the folder to the position illustrated in Fig. 2, or wholly retracted, the motion of the friction-wheel ceases by the contact of said succeeding projection or ear of the friction-wheel with the stop 94. The receptacle is now removed from the folderarms, the same having been released by the spreading of the displacing-arms 7 5, a new blank is applied to the holding-pin 24, the foot-rest is again actuated to release the friction-wheel, and downward pressure is applied to the foot-lever to hold the friction-wheel S3 in contact with the friction-disk 86 until said friction-wheel has made another half-revolution, at the end of which it is again stopped by the engagement of the succeeding projection or ear 96 with the previously-released stop 94.

An important advantage of the construction herein described resides in the fact that the folder-arms, which constitute, with the spider, the exterior member 0f the folder, consist of narrow strips and perform their function without obstructing the view of any portion ofthe blank from which the receptacle is formed. In other words, the entire blank is visible from the time it is placed upon the retaining-pin of the form until the completion of the basket, and hence any flaw or defeet in the construction or in the material is visible, and the receptacle upon the discovery of such defect can be .removed from the machine without waiting until the completion thereof, thus saving the time which would be consumed in completing a worthless article.

Any ordinary or approved construction of stapling mechanism may be used inconnection with the machine embodying my invention; but in the drawings I have illustrated an efficient form wherein the hammer proper, 41, is provided with a hammer-post 103, which fits in a staple-guide 104, formed by slotting a shear-blade 105, said shear-blade being arranged parallel with the hammer proper for retraction thereby. The shear-blade is yieldingly held depressed or receives downwardY movement by means of an actuating-spring 106, and the hammer proper is provided with IOO IIO

a projection 107 to engage a pin 108 on the blade, whereby upward movement is communicated from the hammer to the shear-blade. The hammer-post is provided with lateral webs 109 to operate in staple-receivin g grooves 110 in the staple-guide 104.

Coperating with the hammer and shearblade, as above described, is a staple-former 111, yieldingly held extended in the path of the hammer by means of a spring 112 and having a beveled front end forming a cam by which it may be depressed by means of said hammer. Any suitable tension devices may be employed for feeding staple-wire 113, such as a roll 114C, having a ratchet 115 for engagement by a pawl 116, supported by the hammer-head, in connection with an eccentric roll 117. This staple-wire enters the hammer-head guide 118 through a suitable opening 119 and passes through a seat or notch 120 in the cam-face of the staple-former 111,

whereupon when the shear-blade is depressed with the hammer the proper length of wire is detached to form the clip, and the extremities of the blank thus formed are bent downwardly to lie in contact with the sides of the former. As the downward movement of the shear-blade continues the sides of the clip are forced into the clip-guides 110 below the lower extremity of the hammer-post, which is located at an interval from the lower end of the shear-blade. When the lower end of the shear-blade reaches the surface into which the clip is to be driven, its downward movement is checked, while the downward movement of the hammer continues and thus forces the staple into said material.

While in the above description I have referred to the apparatus as being adapted for driving clips and staples, it is obvious that nails may be substituted therefor and that any suitable construction of stapling apparatus may be employed in connection with the basket-forming devices, and, furthermore, that various other changes in the form, proportion, and the minor detailsof construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention. Furthermore, it will be understood, although not specifically shown or described, that the disk 38 may be mounted loosely on the shaft 37 and means, as a clutch, provided for locking or unlocking the disk with relation to the shaft or to the adjacent pulley 83, so that the drivingshaft shall be left free to be engaged at will either with the staple mechanism or with the folder mechanism.

In Fig. 16 I have illustrated a double arrangement of the improved machine, wherein two are operated simultaneously, the same being arranged in opposite or reversed positions and having their folding devices connected by a bar 121, one end of which is pivoted, as at 122, to allow the rod to be broken or its parts to be deiiected to remove the folders manually when the construction of a receptacle has been completed. In order to 'release the folders, one of the machinesconnected by a sliding joint 124 to facilitate said movement of the machine A independently of the machine B.
